Hi guys ive been on citalopram for 3yrs now and have been great ," normal," whatever that is n now all of a sudden my anxiety is back n I just can't cope, no appetite, tight chest, knot in my stomach, obsessive thoughts, hate being alone, I feel like I'm going crazy. I'm on 20mg n really don't want to up the dose as the side effects of starting citalopram were hurrendous for me. I've had this anxiety 7 days solid n it's terrifying me
